CAR=AX SPECIFICATION forming part of Letters Patent No. 366,529, datedJuly 12, 1887.

Application filed June 13, 1887.

To all whom it may concern.-

Be it known that I, JAMES TIMMS, of O0- lumbus, in the county ofFranklin and State of Ohio, have invented certain new and usefulImprovements in Oar-Axle Boxes, of which the following is aspecification, reference being had to the accompanying drawings.

. My improvements relate altogether to means for securing a lid ofacar-axle box down tightly in place to close the box by means ofspringpower.

I am aware that various applications of springs to lids of ear-axleboxes have been made for this purpose; but my object is to present anexceedingly simple, cheap, and effective organization to accomplish theobject bet ter than has heretofore been done.

I am aware, for example, of Patent No. 42,037, of 1864, and othersrelating to the sub ject, including Patent No. 352,592, of 1886;

and it is in view of these that I have made and now proceed to describemy improvemeals.

In the accompanying drawings, Figure 1 is avertieal longitudinal sectionof a ear-axle box with my invention applied. Fig. 2 is a bottom view ofthe lid detached, and Fig. 3 is a top view of the same.

Referring to the letters upon the drawings, A designates a ear-axle box,and B its lid.

0 indicates a projection or hinge-knuckle, having a hole through it forthe hinge-pintle D, which also passes through the lugs or knuckles E Eof the lid, and thus is formed the hinge-connection between the box andthe lid. The knuckle O operates as a cam, being curved on its upper faceat F and substantially plain on its front face, G.

I provide a hollow curved projection, H, on the upper part of the lid,which may be cast integral with it. A continuation of this hol- SorialNo. 241,179. (No model.)

piece, K, for lifting the lid. This construction of the-lid, includingthe knuckles E, forming it all in one piece, makes it very simple,light, and neat in appearance.

L designates a curved rod, which may be provided with a head, M, andaround which is a coiled spring, N. This curved rod and spring fit intothe curved aperture in the curved projection H of the lid. The springbears against the bottom of the curved projection, near the thumbpieceof the lid, and against the head M, and the head bears against thecam-su rfaees of the hinge-knuckle G. The result is that the spring actsadvantageously to press the lid tightly to place when closed, and alsoto hold it open, so that the lid works closed and firmly open byspringaction, and not liable to stop at any intermediate point. Thecurved line of action of the spring tends directly and veryadvantageously to hold the lid closed.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

1. The combination, with a ear-axle box and its lid hinged thereto andprovided with a hollow curved projection, H, on its upper part, of acurved rod, L, provided with a head, M, and a coiled spring, N, and thecamknuckle O, substantially as set forth.

2. An improved lid for ear-axle boxes, provided with the hollow curvedprojection H, a thumb-piece, K, and the knuckles E E, all formed in onepiece, substantially as set forth.

In testimony whereof I have hereunto subscribed my name.
